build failure (der-protos.h)

[Thomas Klausner <wiz%NetBSD.org@localhost>]

On a 5.99.49/amd64 host, building -current using build.sh -j16 for
amd64 fails for me with:

--- asn1_hdb_asn1.o ---
In file included from
/archive/build/amd64.20110429/usr/include/krb5/der.h:101, from 
asn1_hdb_asn1.c:16:
/archive/build/amd64.20110429/usr/include/krb5/der-protos.h:13: error:

and lots more similar errors. Does anyone else see this?
